Title: Super cavitation propeller for ship equipped with wing piece at rear edge portion of wing
Inventor: MINAMIURA JUNICHI
IPC: B63H1/18
Filed: 1990-04-24
Abstract: PURPOSE:To enhance propeller efficiency even during navigation at low speed while maintaining performance equal to that during navigation at high speed by providing a wing piece thinner than the rear edge portion of a propeller wing in such a manner as projecting backward from the rear edge portion of the propeller wing. CONSTITUTION:A thin wing piece 11 attached to the rear edge portion of a propeller wing 01 prevents eddies formed behind the rear edge portion of the wing by the speed difference between the upper and lower surfaces of the rear edge portion and also by peeling of a boundary layer from being enlarged at the rear edge portion of the propeller wing 01. Therefore the eddies generated by the peeling are not themselves enlarged and also air flows of different speeds on the upper and lower surfaces of the rear edge portion are separated from each other to as far as the rear edge of the thin wing piece 11 and thrust is increased by the effect of extension of the propeller wing. Because the boundary layer is peeled on the thin wing piece 11, friction resistance is small at the wing piece 11 portion. Under the state of super cavitation the thin wing piece 11 is covered with generated air bubbles, so the property of super cavitatdon is not affected at all.

Title: Discharge flow control device for variable-delivery hydraulic pump
Inventor: SHIMOTORI MASAHIKO
IPC: F04B49/00
Filed: 1985-05-22
Abstract: PURPOSE:To facilitate change in the control of flow and pressure in a variable-delivery hydraulic pump, in which the angle of slant rotation is controlled through an actuator by way of controlling a servo valve, by providing it with a controlling means in which output torque is calculated in response to the output from each of a pressure detecting unit and a flow detecting unit. CONSTITUTION:When a device is put in motion, a high-pressure solenoid selector valve 25 is changed over to the upper position by means of a controlling means 11, and the spool 8' of a servo valve 8 is switched by the action of a spring 28 to the right position. Thereby, pressure oil, which is supplied from a hydraulic power source 9 and kept at a constant pressure by means of a relief valve 10, is fed to the small sized chamber 3 and the large sized chamber 3' in an actuator 2, and a piston 4 is moved to the left owing to the difference in area between the two chambers such that the angle theta of slant rotation of the pump 1 reaches a maximum. In addition, when the discharge pressure of the pump 1 is raised to exceed the set pressure, high- speed solenoid valves 23, 24 are opened and closed at great speed resulting from the calculation of output torque as a product of output signals from a pressure detecting unit 21 and a flow detecting unit 22, such that the piston 4 is moved to the right, and the angle theta of slant rotation of the pump is caused to become smaller.

Title: Application of film to piping
Inventor: SUZUKI MASAKI
IPC: B05D7/14
Filed: 1984-05-30
Abstract: PURPOSE:To make it possible to maintain the life of piping over a long period of time by suppressing the spreading and advance of corrosion, by forming projections to the inner or outer surface of the piping to which a film is applied. CONSTITUTION:The inner surface of a pipe is cut so that the shape of each projection is a quadrangular pyramid and triangular grooves can be formed in both spiral and pipe axial directions. The height of each projection is set to about 1.5mm. and the angle of each side surface of the quadrangular pyramid to 60 deg.. By this structure, even if a flaw is generated in a film, the flaw is stopped at the leading end of each projection while the liquid sump surrounded by the interface of the film and a metal can be formed as the flaw part is corroded and corrosion advances and an electrolyte is held at high concn. and, therefore, the advance of corrosion is reduced.

Title: Organic electrolyte battery
Inventor: TAKEMORI MASAMI
IPC: H01M6/16
Filed: 1980-08-07
Abstract: PURPOSE:To increase the operational voltage at low temperature by using a negative electrode made of lithium, and adding a given amount of a mercury salt to the electrolyte. CONSTITUTION:A battery includes lithium used as a negative electrode 3, and an electrolyte containing 0.5-5.0wt% of mercurous chloride, mercuric chloride, mercurous nitrate, mercuric nitrate or the like. The amount of such a compound contained in the electrolyte perferably is 0.175-1.75mg per unit surface area of the former lithium. The electrolyte, which may be a usually used one, is preferred to be prepared by dissolving perchlorate and lithium borofluoride in propylene carbonate, 1,2-dimethoxyethane, tetrahydrofuran, gamma-butyfolactone, or a mixture solvent consisting of some of these solvent. A positive electrode 5 for the battery is made of manganese dioxide, iron sulfide, copper sulfide, copper oxide, carbon fluoride, silver chromate or the like. Since amalgamation of the former lithium enables the mainteance of the surface activity, any decrease in the operational voltage caused at low temperature can be prevented. Besides, unusually high voltage seen at the initial discharge stage of a battery constituted by using a positive electrode made of manganese dioxide, can be removed.

Title: Frequency multiplying circuit
Inventor: YAMAGUCHI TOSHIYUKI
IPC: H03K5/00
Filed: 1979-08-27
Abstract: PURPOSE:To make it possible to extract easily a rectangular wave of a frequency twice greater than that of an input rectangular wave, by inputting a 90 deg.-out-of-phase rectangular wave to an exclusive-OR element. CONSTITUTION:Original signal 1 is waveform-shaped by waveform shaping circuit 2 into a 50%-duty rectangular wave. To one input terminal of exclusive-OR C, the 50%-duty rectangular wave is applied as it is. To the other input terminal, it is applied by way of the integral network consisting of C1 and R1. The rectangular wave is converted by the integral network into a triangular wave, which is inputted to the exculsive-OR element. The triangular wave operates on the logic circuit as a rectangular wave which is 90 deg. out of phase with the original rectangular wave, so that a 50%-duty rectangular wave of a frequency twice greater than that of the input wave can be obtained at the output side.
